TYPE-WRlTlNG MACHIN E.

SPECIFICATION forming part of Letters Patent No. 687,000, dated November 19, 1901.

Application filed April 4, 1898. Serial No. 676,372. (No modell) To ctZZ whom it may concern:

Be it known that I, WALTER J. BARRON, a citizen of the United States, and a resident of the borough of Brooklyn, county of Kings, and city and State of New York, have invented certain new and useful Improvements in Type-Writing Machines, of which the following is a specification.

The main object of my invention is to provide a cylindrical platen With a simple and effective card holder or clamp; and'to this end it consists, primarily, in combining with the platen shaft or axle a card-holding clamp or device which is adapted to be raised or projected by a movement of said shaft or axle to enable the insertion orintroduction oftheleading edge of a card or stifi piece of paper and to then clamp or firmly hold the same upon the platen to insure its proper feed therewith in line-space direction, and, secondarily, in certain other features of detail construction and arrangement, all as will be hereinafter more fully described,and particularly pointed out in the appended claims.

In the accompanying drawings, Figure 1 represents a portion of the carriage of a Densmore type-writingmachine and acentral vertical section through the platen, which is provided with my improved card-holder. Fig. 2 is a vertical cross section thereof taken at the line w on of Fig. 1. Fig. 3 is an end view of the platen detached and looking at the righthand end thereof. Fig. 4 is a vertical section taken at the line a u of Fig. 1. Fig. 5 is a partial central vertical longitudinal section through a platen and showing a cardholder of different detail construction. Fig. 6 is a vertical cross-section taken at the line a z of Fig. 5. Fig. 7 is a view similar to Fig. 5, but showing a further modification of construction of the card-holder. Fig. 8 is a vertical cross-section thereof taken at the line y y. Fig. 9 is a view similar to Figs. 5 and 7, showing a still further modification of construction of the card-holder. Fig.10 is a ver- 7 r of Fig. 5.

Referring to Figs. 1, 2, 3, and 4, l desig nates a platen frame or carriage; 2, the

platen; 3, the platen shaft or axle; 4, the pa 1 per-table; 5, an apron or deflector, and 6 a paper guide or finger. The platen-axle is mounted to turn in bearings 7 in the platencarriage, and the platen is attached to said axle, so as to turn therewith, for convenience of rotation the platen-axle being provided at either end with a hand-wheel 8. The platen consists of a hollow core 9, preferably of wood, a rubber sheath or cover 10, and circular heads 11 and12, fixed to the ends of the platen, the head 12 being provided with ratchet-teeth for cooperation with the linespace mechanism in the usual manner. The platen-axle passes through said heads and through the center of the core, and near each of said heads the said axle is flattened, as at 13, and provided thereat with a pin 14, which enters an obliquely-arranged slot 15 at the inner end of a leg or projection 16, extending substantially radially inward from a clamping-bar 17, which is disposed longitudinally of the platen for substantially its whole length and which is arranged parallel with the axis of the platen in a substantially radial slot 18, cut through the core and through the rubber sheath, as shown more clearly at Fig. 2. The uppermost edge of the bar 17 is bent at an angle to the body, so as to provide a small lip or flange 19 for holding the edge of the card upon the surface of the platen. Surrounding the platen shaft or axle is a coiled spring 20, which at one end bears against the head 11 and at the opposite end against a collar 21, fast on said axle, and the tension of said spring is such as to force the shaft toward the right and the pins thereon to the upper ends of the oblique slots 15, and thereby cause the holding-bar 17 to be drawn in and held with the lip 19 down upon the surface of the platen. Then the shaft oraxle is slid endwise toward the left, which maybe done either by pushing upon the right-hand knob or wheel 8 or by pulling upon the lefthand knob, the pins 14 14 act upon the upper walls 22 of the slots and cam or push the bar 17 radially outward, and when the pressure or pull is released the spring 20 causes the shaft to slide in the opposite direction and the pins 1t 14: to act upon the lower edges 23 of the slots and draw or wedge the bar downwardly or inwardly. The shaft is connected to the platen by a pin 24, which passes through a central slot 25 in the left-hand hub 26 of the platen and through a hole centrally of the shaft, the pin having a tight fit in said hole, and by reason of this construction the shaft and platen are caused always to turn together, while at the same time the shaft maybe slid endwise independently of the platen. Then the shaft has been slid toward the left and the holding-bar 17 forced outwardly, the leading edge of the card or the like is passed under the lip or flange 19, which securely clamps the same under the tension of the spring 20 when the pressure upon the shaft is released and the parts are restored to normal position. The platen may then be rotated until the desired portion of the card is brought to the printing point or plane, when the writing may then be begun. The platen may be rotated either by its shaft or axle or by the usual line-spacing devices. On the completion of the writing uponv the card the shaft is pushed endwise again, so as to release the card from the holding-lip 19, which acts to positively carry the card around with the platen. It will be understood, of course, that in conjunction with the platen may be used the usual pressure-roller and paper-guides for keeping the card close against the platen at or in the vicinity of the printing-point, so as to obtain the best impressions, as common heretofore. At 27 are represented the heads of two small nails or screws, which are driven into the surface of the platen at the righthand end thereof, and these or other suitable devices may be used as a guide for inserting the card, as will presently be explained. 28 denotes the head of another nail or screw, also driven into the platen at its right-hand end for the purpose of serving as a guide for the beginning of the printing, as will also presently be explained. I prefer to rotate the platen to the position shown at Fig. 3 when about to insert a card and to drop or push the card substantially vertically into the space between the surface of the platen and the flange 19 and then after the card has been clamped to rotate the platen to the position shown at Fig. 4 and so that the flange 19 is carried forward past the longitudinal vertical plane through the printing-point at whichithe types strike in order that the types shall not come in contact with the said metallic flange 19. The devices 27 and 28 are provided for facilitating these operations. When the device 27 is brought around uppermost or to the position shown at Fig. 3, the operator is thereby informed that the clamp 19 (which at this time in practice is out of sight, assuming the operator to be seated at the front of the machine, as usual) is in proper position to receive the card it passed down in substantially a vertical direction, and hence the operator will be enabled to conveniently and properly insert or introduce the card at the most desirable or favorable place without the necessity for actually seeing the clamp, it being only necessary while the clamp is projected to pass the leading edge of the card down in contact with the rear side of the platen until such edge abuts against the bar 17 and comes under the lip or flange thereof. Then this has been done and the edge of the card has been clamped, the platen may be turned directly by rotation of the shaft until the device 28 is uppermost or in the position shown at Fig. 4-, at which time the operator will know that the clamp has been carried past the printingplane and that it is safe to operate the types without danger of contact with the clamp,thus rendering it unnecessary to lift the platen to ascertain this fact.

Referring to Figs. 5 and 6, the construction therein exhibited is the same in all respects as that hereinbefore described with reference to Figs. 1 to 4, excepting that the clampingbar instead of being provided with a lateral lip or flange is slotted lengthwise, as at 29, near its outer edge to receive the leading edge of the card, the bar 30, formed by said slot, serving as a flange to clamp or hold the card upon the platen under the tension of the spring 20, which is used in this construction at the left-hand end, as in the construction shown at Fig. 1. This clamping-bar being made of very thin stock requires but a narrow slot in the platen to receive it and is located at a point where the types do not strike. Hence with this construction the card-holding platen may be used for regular work on paper.

Referring now to Figs. 7 and 8, a construction like that shown at Figs. 5 and 6 is exhibited with the additional feature of an olfset flange 31, formed out of the metal of the bar 17 and provided as a stop to limit and determine the extent of introduction of the card into the slot 29.

Referring now to Figs. 9 and 10in this construction, the bar 17, which is provided with a lip 19, as in Fig. 1, is connected to the shaft or axle 3 at near each end by an obliquely-arranged link 32, pivoted to said bar and to said axle, and in place of a coiled spring surrounding the axle, as before, a coiled spring 33 is attached at one end to said bar and at the other end to said axle. lVhen the axle is pressed toward the left, the links 32 cause the bar 17 to move outwardly, and when the pressure is released the spring acts to return the bar, the card being inserted, as before, when the bar is projected.

Referring now to Figs. 14, 15, 16, and 17, the construction there shown is somewhat similar again to that illustrated at Fig. 1. In this modification the card-clamping devices proper are, however, differently constructed for the purpose of eliminating the clampingbar, so that the platen may be used with paper for ordinary work. In this construction the rubber sheath or cover 10 need not extend for the entire length of the platen and the core or hollow wooden cylinder 9 is slitted or cut through substantially radially and at substantially diametrically opposite places, as indicated at 18 and 18 and fitted into these slots or cuts at each end of the platen is a metallic device 34, consisting, essentially, of two parallel arms or members 35, a connecting-bar 36, and a hook 37. Each connecting bar or member 36 is provided with an oblique slot 38, which is engaged by the pin 14, projecting from the shaft or axle 3. 39 is a detachable clamping bar or plate formed at each end with a longitudinal slot 40 for the passage therethrough of the hooks 37 in the operations of attaching and detaching the bar. In order to attach the bar, the slot is alined .with the hooks 37 and passed down over the right-hand end 42 is slid under the right-hand hook 37, thus locking the bar to the devices 34. and connecting it to the platen and its axle. When the axle is pressed leftward, as heretofore described, the two devices or frames 34 are projected and the bar 39 is lifted from the platen far enough to enable the edge of the card to be placed thereunder, and when the pressure is released the spring returns the parts and the card is clamped upon the platen. When it may be desired to use the platen without the card-holder, the bar 39 is detached by sliding it endwise of the platen toward the right until the hooks 37 and the slots 40 register, whereupon'the bar or plate may be removed.

It will be observed that-in each of the structures shown there is a connection between the clamping bar or plate and the shaft near each end of the bar, so that the bar is moved to equal extents at both ends and the same amount of pressure is exerted upon both ends of the bar to eiliciently clamp the card in place.

While I prefer to use an elongated lip, flange, or bar extending for substantially the whole length of the platen and have shown this preferred form of construction in all of the views, it will nevertheless be understood that this device may be cutaway at intervals, so as to provide only short lips, flanges, bars, or fingers, for in some cases they would serve the purposes satisfactorily; but the elongated lip or flange is adapted for all sizes or lengths 1.
